Gather all the materials listed out to begin.
First, chop a block of soap into smaller pieces and melt them. You can either melt them in a microwave or place the blocks in a container and place it in a pot of boiling water. Keep stirring the soap so it melts evenly and also to keep it from burning.
When it has melted, you can add a few drops of essential oil if you want to. Then, quickly pour the soap into the mold—silicone or plastic/paper cups and containers are all adequate—before it hardens.
Spray the surface with isopropyl alcohol to get rid of any bubbles.
You can experiment with decorating your soap. You can layer the molds with herbs and dried flowers and pour the soap over it. Or, you can mix the flowers and herbs into the soap and pour it into the mold, too.
You can also add a few drops of liquid soap colorant or mica powder to color the soap. Stir the color in to mix it thoroughly. You can either marble the soap,or, if you want clear and distinguishable layers, allow the previous layer to harden, spray isopropyl alcohol over it, and then pour the second color over it.
Let the soap dry for 4-6 hours.
Wrap the soap in cling film, paper, or cheesecloth and decorate it with twine or ribbon if you’re looking to gift them.
